iShape-Antenna Creation. For the creation of iShape-Antenna, we first prepare a carton with a white cushion at the bottom, then randomly and elaborately place antennas in it to generate various scenes. Above the box, there is a camera with a light that points to the inside of the box to capture the scene images. We collect 370 pictures and annotate 3,036 instance masks then split them equally for training and testing. The labeling is done by our supplier. We have checked all the annotations ourselves, and corrected the wrong annotations. Although iShape-Antenna only contains 370 images, the number of instances reaches 3,036 which is more than most categories in Cityscapes [1]} and PASCAL VOC [2]}.
